    (54) Digital recorder


    (57) A buffer (1007) serves as a sub-memory with respect to a hard disk (1012) and performs a data recording/reproducing operation. With this arrangement, even if the access rate of data in the hard disk (1012) is not so high, data transfer between the hard disk (1012) and an audio I/O (1009), a MIDI I/O (1010), and image I/O (1011) can be performed via the buffer (1007), and audio, MIDI, and video data can be simultaneously and selectively recorded/reproduced.
